Like all mouthwashes that effectively fight plaque and gingivitis, Crest Pro-Health Rinse can contribute to temporary, surface-level brown tooth discoloration, which is reported by a small percentage of individuals. Tooth discoloration could actually be one indication, in some people, that the product is working: after the rinse kills germs in your mouth, the dead germs can collect on the tooth surface and create the appearance of a brown stain. Tooth discoloration could be exaggerated by many other factors, such as existing tartar on teeth, consumption of colored beverages like coffee, tea and/or red wine, or tobacco use. Brown tooth discoloration from use of mouthwashes that effectively fight plaque and gingivitis is not harmful. It is reversible - and largely preventable - through options like brushing with a power toothbrush and tartar-control/whitening toothpaste, flossing, and visiting the dentist regularly. Read More

Adding a rinse to your oral hygiene routine ensures a more comprehensive clean, but does the burning sensation mean the mouthwash is working or is it a symptom of something else? Most mouthwashes are formulated to kill bad breath germs and help fight plaque bacteria, but the burning sensation you feel? That’s alcohol*. Look for a gentler, yet effective clean with an alcohol-free mouthwash. You’ll experience less burn and fewer harsh symptoms that alcohol can cause.
